CLEVIS FOR COUPLINGS.

Specification of Letters Patent.

Patented Sept. 10, 1912.

Application filed November 13, 1911. Serial No. 660,047.

To all whom it may concern:

Be it. known that I, EDMUND P. KINNE, a citizen of the United States,residing at Alliance, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Clevises for Couplers,of which the following is a specifica tion.

My invention relates to car couplers and has particular reference to anovel clevis for use in connection therewith. I

Many couplers of the J anney type, which are provided with the usualshank, head, knuckle and lock, are so arranged that the lock is liftedby a link pivoted to the look within the recess in the coupler head.This link usually projects out through the top wall of the coupler headand has attached thereto a clevis to which the lifting chain or lever isin turn secured. In other forms the lock has a solid portion whichprojects through the top wall and completely fills the opening. This ofnecessity is not true in the construction employing a link, inasmuch asthere must beconsiderable clearance around the link to permit thenecessary free movement and prevent binding. However, where suchconstruction is used it has been found that the portion of the openingleft uncovered accumulates deposits of dirt and snow and interferes withthe eflicient operation of the coupler. Furthermore it is not uncommonfor the link when provided with a clevis of common form, to becomewedged against the walls of the opening, itsremoval therefrom beingdifiicult. This cannot occur when my clevis is applied.

The principal. object therefore of my invention is to provide a cleviswhich shall in' addition to performing its usual functions completelyclose the lifter hole when the parts are in their normal operativeposition, and also prevent the wedging of the link, inasmuch as theupper end of the link can never get below the plane of the opening.

A further object is the provision of a clevis which shall be very strongand durable and which shall be so constructed that the wear may notinterfere witlrits functions. 7

Other and more particular objects will appear hereinafter.

My invention will be more readily understood by reference to theaccompanying drawings, wherein;

Figure l isa plan view of a coupler having my novel clevis appliedthereto; Fig. 2 is a fragmentary elevation on a large scale, and, Fig. 8is a section on the line 33 of F ig. 2.

Referring more particularly to the drawings, it will'be seen that in thecoupler shown in Fig. l, which is of any preferred construction, thereis a shank l0, coupler head 11, knuckle 19, and knuckle pivot pin 13. Inthe top wall 14 of the coupler head is formed an opening 15, throughwhich the upper end of the lock lifter 16 projects. This lifter or linkhas a body portion, the upper end of which is narrowed as at 17, andperforated for the accommodation of a pin 18, which pin serves to securemy novel clevis to the lifter. This clevis is composed of a singleforging or casting and has a loop 19, the ends 20 of the clevisspherical in outline and having registering openings 21 for theaccommodation of the being hemi pin 18. One of the registering openingsis 4 counter-sunk to accommodate the head of the pin 18. A suitablecotter 22 is provided to hold the pin in place.

It will be seen that the opening 15 through the topwall of the coupleris provided with a head around the upper portion and this furnishesaflared seat on which the hemispherical ends 20 of the clevis may restwhen the parts are in normal position. In this way a tight joint issecured, effectually preventing the entrance of dirt or snow andproviding at the sametime a flexible connection. It will also beobserved that there is an unusually large amount of metal at theattaching end of the clevis and. that there is no possibility of thedevice becoming inoperative through wear either of the coupler wall orof the clevis.

Various modifications may be made in the structures herein shown anddescribed, all Without departing from the spirit of my invention.

I claim; cal in form and adapted, when associated A device of the classdescribed comprising, with said lifter, to substantially entirely 0 incombination, a coupler having a top wall close said opening,substantially as deprovided with an opening therethrough, a scribed.
